Thx a lot, all of your considerations and suggestions were very interesting.
Actually, I thought I already changed the service to run as Administrator, but I checked
and it was not...
So I did it, and now it works fine! :)
I don't feel it so unsafe to run it as Administrator instead of local system.

Thanx again,
Gabriele.

Oggetto: Re: [Bacula-users] backup nas on windows fd

I assume that when you run the script manually, you are logged on as
user Administrator. Bacula-fd probably runs the script as user bacula,
or some other user.

There are several things that could go wrong here. I don't remember off
the top of my head what error 59 is, but I believe it is related to some
kind of logon failure. First, you may be using the wrong administrator
account. You don't specify the realm of Administrator, so Windows may be
using the local administrator account or the domain administrator
account when you really may have meant to use the NAS Administrator
account, or vice versa. In particular watch out for that if the service
account you are using is a local account but the account you are using
for testing is a domain account, or vice versa.

Second, Windows has a limitation: you can only be logged onto each
server as one user at a time. This logon information actually stays
around even after you disconnect all drives, printers etc. from that
server - basically, the only way to get rid of it is to log out of your
local session. This is actually a limitation of the client
implementation, so it doesn't matter if there is a NAS or some other
device on the server end.

So if, during your manual testing, you already connected to the NAS at
some point, Windows will actually ignore the /user:Administrator option,
and reuse whatever user you have been logged on as before. The bacula
service won't have access to such a preexisting connection.

Finally, here is a tip for testing things in a service account that
doesn't allow regular logins, at least in Windows 2003 (I haven't needed
it in 2008 yet). I sometimes use this trick with the Local System
account. It's actually technically a security flaw as it lets you as
administrator get even into directories that you don't have permission
to - like roaming profile directories, for instance -, but when
debugging scripts for services, at times it comes in as a godsend.

In Control Panel, find "Scheduled Tasks". Create a new scheduled task
that simply launches C:\Windows\System32\cmd.exe. Specify your bacula
user and password. Pick a time about two minutes in the future. Then you
wait. At the appointed time, a command window will pop up, logged on as
the correct service account. Test to your heart's content, run the net
user command as the actual user, and see what happens.
